Welding requires cutting the steel beams in advance, and bolting requires a large number of bolts, which is very labor-intensive. Therefore, it is necessary to design a new type of steel beam connection structure to solve the above problems. Utility Model Content

[0011] Preferably, a magnetic block is fixedly mounted on one side of the inner cavity of the storage slot.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The connection structure of the steel beam is achieved by inserting the first steel beam into the first fixed frame, and inserting the two second steel beams into the two second fixed frames respectively, and finally rotating the threaded rod. The rotation of the threaded rod drives the limit column to descend. After the limit column descends, it can push the square rod to the inner side of the movable groove by contacting with the inclined surface of one end of the square rod. At this time, the movement of the square rod drives the movement of the clamping plate. After the movement of the clamping plate, the first steel beam and the two second steel beams can be clamped and fixed. After clamping and fixing, the bolts can be screwed into the inside of the first steel beam and the second steel beam through the bolt holes to achieve the effect of strengthening the fixation of the first steel beam and the second steel beam, which effectively saves manpower and improves the efficiency of connecting steel beams.

[0014] 2. The connection structure of the steel beam rotates the threaded rod so that the threaded rod continues to drive the limit column to descend. After the limit column descends, it drives the receiving slot to descend. The storage slot descends and drives the magnetic block to descend. After the magnetic block descends, the square rod can be sucked into the inner side of the storage slot, so that the clamping plate no longer clamps the first steel beam and the second steel beam, thereby facilitating the removal of the first steel beam and the second steel beam.
